Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
The Act of 1704 encouraged the import of naval stores form New England, offering £4 per ton of tar or pitch, £3 per ton of resin of turpentine, and £1 per ton of masts and bowsprits (40 cubic feet). The Act of 1705 forbade the cutting of unfenced or small pitch pine and tar trees with a diameter less than twelve inches.
It does this by collecting and processing organic forest products refined from slash pine and longleaf pine trees (genus Pinus). The naval stores industry was associated with the maintenance of the wooden ships and sailing tackle of pre-20th century navies, which were caulked and waterproofed using the pitch (a product made with tar) of the ...
Wood tar is still used as an additive in the flavoring of candy, alcohol, and other foods. Wood tar is microbicidal. Producing tar from wood was known in ancient Greece and has probably been used in Scandinavia since the Iron Age. Production and trade in pine-derived tar was a major contributor in the economies of Northern Europe [7] and ...
Climate change adaptation has garnered more importance in UNFCCC negotiations in the 2020s as opposed to older times, when mitigation was given more focus. Silvopasture systems which integrate trees and other woody plants along with crops, forage and livestock are a highly sustainable strategy that has huge adaptive capacity, besides its mitigation potential.
The best tar came from pine, thus pinewoods were cut down for tar pyrolysis. The residual charcoal was widely used as substitute for metallurgical coke in blast furnaces for smelting. Tar production led to rapid local deforestation. The end of tar production at the end of the 19th century resulted in rapid re-forestation of affected areas.
Turpentine may alternatively be extracted from destructive distillation of pine wood, [3] such as shredded pine stumps, roots, and slash, using the light end of the heavy naphtha fraction (boiling between 90 and 115 °C or 195 and 240 °F) from a crude oil refinery. Such turpentine is called wood turpentine.
Industrial agriculture is a form of modern farming that refers to the industrialized production of crops and animals and animal products like eggs or milk.The methods of industrial agriculture include innovation in agricultural machinery and farming methods, genetic technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, the ...
